Das kleine Muffelmonster auf Klassenfahrt

A class trip - of course, the little grumpy monster wants to join in! It's obvious! But Moritz is not happy about it at all. After all, his grumpy monster is a secret, and he wants to keep it that way! "Oh no!" pouts the grumpy monster. Now it's in a bad mood and can't even return to its monster world. So, the grumpy monster sneaks into Moritz's backpack... Luckily! Because during tracking in the forest, on the night hike, and while shooting at the goal wall, it proves to be a super strong friend. And a great surprise is waiting for Moritz at the end too!.
